Samsung SSD 870 EVO 1TB Review

Rating: 8.0.

The latest drive to join Samsung's 2.5in SSD series is the SSD 870 EVO, which uses the lastest in-house sixth-generation V-NAND. We review the 1TB model, with a UK MSRP of £135.49 – is it worth the cash?

At launch the SSD 870 line-up comprises of five capacities; 250GB, 500GB, 1TB (the drive we are reviewing here), 2TB and the flagship 4TB model. The drives use the latest 6th generation Samsung 1xx layer V-NAND in combination with an MKX controller and LP-DDR4 cache.

The official Sequential performance figures for all the new drives are up to 560MB/s for reads and up to 530MB/s for writes. Random performance is quoted as up to 13,000 IOPS for reads and up to 36,000 IOPS at a QD1 and up to 98,000 IOPS and 88,000 IOPS for read and writes respectively at QD32.

Data security is provided by AES-256 full disk encryption and the drive supports TCG/Opal v2.0 and IEEE1667.

Samsung quote an endurance figure for the 1TB drive of 600TB TBW and back the drive with a 5-year warranty.
